Specifically, there are four situations to trigger 5% fuse: trigger before (1) 14:42, and resume trading after 15 minutes. For example, 14:3 1 triggers 5% fuse, and 14:46 resumes trading; (2) If it is triggered between 14: 42 and 14:45 (excluding 14:45), the transaction will be resumed at 14:57, and call auction will end. If 14:43 triggers a 5% fuse, then 14:57 resumes trading and conducts closing bidding. (3) If triggered by14: 45 to 14:57 (excluding 14:57), the trading will be suspended until the market closes, and the trading will not be resumed on the same day. (4) If it is triggered on or after14: 57, it will not be blown on that day, and call auction will continue to close its positions until the market closes.
There are two situations to trigger 7% fuse: if it is triggered before (1) 14:57, the trading will not be resumed on the same day, and the relevant securities will be fused to the close; (2) If it is triggered on or after14: 57, it will not be blown on that day, and call auction will continue to close its positions until the market closes.
In addition, for the delivery date of non-stock index futures contracts, if the fuse duration is insufficient in the morning, it will be replenished after the market opens in the afternoon, and the lunch break is not included in the fuse duration. For example, 1 1:27 triggers 5% fuse, then 13: 12 resumes trading.
